Abstract

Abstract Purpose Peptic ulcers, common digestive system disorders, often lead to perforation, which is associated with high mortality. Given the potential for underlying malignancy in gastric ulcers and perforations, this study focuses on assessing the frequency of cancer in gastric biopsies of patients with perforated pre-pyloric gastric ulcers. Methods This cross-sectional study involved 175 patients of all ages, both genders, with perforated pre-pyloric gastric ulcers in 2021–2022, who underwent emergency laparotomy surgery and with a definitive diagnosis of gastric ulcer perforation. A full-thickness sample was taken from the margin of the perforated pre-pyloric gastric ulcer for pathological examination to detect gastric malignancy. Results The patients' average age was 65.69 years, with a median of 65 years. All histopathological examinations of the gastric ulcer samples indicated benign conditions. Among the patients, 54.3% had a history of gastric ulcers, 37.7% had diabetes, 25.7% had hypertension, and 25.7% had both. Additionally, 1.7% suffered from chronic kidney failure, 1.1% from chronic liver failure, and 0.8% had other conditions like cardiovascular diseases. In total, 4.6% patients had a history of corticosteroid use, 66.9% patients had a history of NSAID use, and 58.9% patients had drug addiction. Conclusion Our study found no signs of cancer in the biopsies of patients with perforated pre-pyloric gastric ulcers; all cases showed benign pathology. This suggests that using gastric ulcer perforation alone as a reason for biopsy may need more investigation to ensure its accuracy and relevance.

A duodenal ulcer is typically characterized by severe upper abdominal pain that improves after eating. In contrast, gastric ulcers can cause pain that worsens after eating, often described as a burning or dull ache. Additional symptoms may include bloating, vomiting, weight loss, or loss of appetite (2). About one-third of elderly individuals with gastric ulcers do not exhibit any symptoms. A variety of factors can cause complications in patients with PUD, including Helicobacter pylori (H. pylori) infection, non-steroidal anti-inflammatory drugs (NSAIDs), and low-dose aspirin. These factors can lead to complications, including bleeding, perforation, and stomach obstruction, with bleeding occurring in approximately 15% of cases (3, 4). Perforation, one of the most lethal complications associated with gastric ulcers, can develop in various locations, including the esophagus, stomach, duodenum, jejunum, and multiple segments of the small and large intestine (5). The inflammation and scarring resulting from gastric ulcers can further narrow the duodenum, resulting in symptoms of severe obstruction, vomiting, and sometimes hematoma formation. In certain cases, complications stemming from stomach ulcers can affect adjacent organs, giving rise to ulcers in the pancreas or liver (2, 6). Pre-pyloric ulcers have the highest perforation risk, followed by duodenal ulcers (5). The classic triad of abdominal pain, tachycardia, and abdominal rigidity characterizes gastric ulcer perforation (7). In many cases of PUD, surgical repair (either open or laparoscopic) may be necessary, although non-surgical approaches can be considered for selected patients (8). There can be a significant loss of fluid in patients with intestinal perforations. Depending on the type and volume of substances released from the digestive system, electrolyte imbalance can vary in severity. To minimize such disturbances, perforated patients require expeditious operative management (9). Regardless of the type of surgery employed for local control or definitive ulcer surgery, obtaining a biopsy from the ulcer margin is crucial in all cases of gastric perforation to rule out gastric carcinoma (10). The significant distinctions between stomach and duodenal ulcers significantly influence patients' surgical decisions. Notably, gastric ulcers may carry a risk of malignancy, underscoring the importance of complete ulcer excision or, at the very least, conducting a biopsy through an open surgical approach. Furthermore, patients with gastric ulcers are typically older and have a higher number of risk factors, which increases the postoperative mortality risk within this patient group (11, 12). Although less than 1% of gastric ulcers are premalignant, the relatively high incidence of cancer (9%) in cases of gastric perforation suggests that malignancy often underlies gastric ulcers in perforated patients (5). Given the elevated surgical risk associated with stomach ulcers, particularly in elderly individuals with multiple comorbidities, conducting a biopsy is crucial to confirm malignancy as the underlying cause (13). In our study, we performed biopsies on patients who arrived at the emergency room with clinical symptoms and approved diagnostic assessments suggesting a need for surgical intervention due to a perforated pre-pyloric gastric ulcer. During emergency surgery, we determined the frequency of confirmed malignancy by examining pathology reports derived from biopsies of the ulcer's wall, thus ensuring the diagnosis of a perforated pre-pyloric gastric ulcer. Material and Methods Study Design This study employed a cross-sectional conducted at Sina Hospital in Tehran between 2021 and 2022. The study included 175 patients of all ages, men and women, diagnosed with a perforated pre-pyloric gastric ulcer. To confirm the diagnosis of gastric perforation, all enrolled patients underwent emergency exploratory laparotomy surgery. All participants or their parents provided written informed consent. The study was approved by the ethics committee of Tehran University of Medical Sciences (ethics code IR.TUMS.SINAHOSPITAL.REC.1400.079), and followed the guidelines of the Helsinki Declaration and the Iranian Ministry of Health and Medical Education. Study Population The inclusion criteria consisted of patients diagnosed with perforated pre-pyloric gastric ulcers and with no indication of gross mass. Patients with ulcers in the antrum, near the lesser curvature, combined gastric and duodenal ulcer, and ulcer in the proximal stomach or cardia (High on lesser curvature) were excluded. Also, who had previously undergone distal gastrectomy surgery due to gastric perforation and those with a final diagnosis of perforated gastric cancer were excluded from the study. Additionally, patients with a proven history of gastric cancer or cases where the tumor was visible were excluded. Data Collection During the surgical procedures, full-thickness samples were obtained from the margin of the perforated prepyloric gastric ulcer. These biopsy samples of 175 patients, underwent pathological examination to assess the presence of gastric malignancy. In addition to pathological findings, histopathological analysis aimed to confirm the existence of malignancy in various forms, such as adenocarcinoma, lymphoma, or stromal tumors. Independent variables were collected, including demographic information (age, sex), medical history (previous gastric ulcer disease, diabetes, hypertension, chronic kidney disease, and liver failure), and drug history (daily and continuous use of NSAIDs and corticosteroids for at least 2 weeks) and the presence of drug addiction among patients. Data for these independent variables were gathered using a researcher-designed checklist administered during the patient's initial hospitalization. Data Analysis The data collected was entered into Excel software for initial preparation. Descriptive statistics were then applied to the data, including central indices (mean, median, and mode) for quantitative variables and dispersion indices (variance, standard deviation, range of changes, coefficient of variation). For qualitative data, the descriptive statistics included frequency, percentage, and prevalence. All necessary diagrams, such as a bar and pie chart, were generated. In the inferential statistics section, parametric tests, specifically the chi-square test, were employed to examine the study hypotheses after confirming the normality of the data distribution. Statistical analysis was conducted using SPSS software version 25, with a significance level of p < 0.05. Results In this study, we included 175 patients with perforated pre-pyloric gastric ulcers. All patients' gastric ulcer samples were reported to be benign in the histopathological findings, and no gross masses or tumors were detected, precluding a comparison of demographic and clinical variables with histopathological results. The average age of patients was 69.65 years, with a median of 65 years old and ages ranging from 50 to 81 years. A total of 57.1% of the patients were males, and 42.9% were females. The patients were nearly evenly divided by age, with 48.6% being 65 or younger and 51.4% older than 65. Additionally, 45.7% of patients had a history of gastric ulcers, whereas 54.3% did not (Table 1 ).

Regarding the frequency and percentage of histories of corticosteroid use, NSAIDs, and addiction among study patients, 4.6% had a history of corticosteroid use, 66.9% had used NSAIDs, and 58.9% had a history of drug addiction (Table 2 ).

Also, there was no significant difference between men and women regarding gastric ulcer history, corticosteroids, and NSAID usage. However, the prevalence of drug addiction was significantly higher in men than in women (P < 0.001) (Table 3 ).

Stomach ulcers significantly contribute to these malignancies. Although biopsies are commonly used in perforated gastric ulcers in the pre-pyloric region, our study indicates a potential need to revise this strategy. A key finding is the absence of malignancy and gross mass or tumor in gastric biopsies from patients with perforated pre-pyloric stomach ulcers, all showing benign pathology. This raises the question of whether biopsies are necessary for all cases, as accurate malignancy diagnosis in gastric biopsies requires a minimum of 8 samples from various parts of the lesion (15). Our research is among the few studies that examine malignancy rates in patients with perforated gastric ulcers. Comparing these findings with other studies is challenging due to the focus on peptic ulcer risk factors in other studies. Due to this finding, the relationship between perforation and demographic or clinical variables couldn't be explored. However, chronic inflammation caused by Helicobacter pylori in patients with perforated peptic ulcers remains a significant medical concern in gastric cancer development (16). In the context of the relationship between H. pylori infections and gastric diseases, the comprehensive meta-analysis by Shirani et al. (17) is particularly enlightening. This study, encompassing 149 studies with a massive sample size of 352,872 individuals, delves into the global prevalence of gastric cancer among H. pylori-infected persons. Through extensive data extraction and statistical analysis, it sheds light on the prevalence and characteristics of gastric cancer in those afflicted with H. pylori. A vital aspect of this relationship is the role of specific bacterial features in causing cancer. Notably, certain H. pylori strains produce a toxin named CagA. Once injected into stomach lining cells, this toxin can induce carcinogenic changes, promoting cell growth and motility, leading to chronic inflammation. Epidemiological studies underscore that strains positive for CagA are more strongly associated with non-cardia gastric cancer than CagA-negative strains. Lifestyle factors also influence the risk of H. pylori-induced stomach cancer. Smokers infected with H. pylori, for instance, face a higher risk of developing stomach cancer compared to non-smokers with the infection (18). Additionally, diets high in salt and processed meats are linked to an increased risk of stomach cancer, potentially exacerbating H. pylori colonization and CagA entry into gastric cells (19, 20). Although our study did not evaluate lifestyle factors such as smoking, salt intake, and meat consumption, these aspects are crucial in understanding the overall risk landscape for gastric cancer in H. pylori-infected individuals. Therefore, it was essential to consider these factors alongside the biological characteristics of H. pylori and its interaction with gastric pathology. In our study, gastric ulcer perforation was more common in men than women, with the incidence of gastric ulcer perforation being 1.3 times higher in men. Comparatively, Bhattarai et al.'s (21) study found a 1.9 times greater prevalence of gastric malignancies in men than women. Similarly, Ramakrishnan et al. (22) reported the ratio to be 2 times higher in men. In their study, Hearnshaw et al. (23) also reported that the incidence of upper gastrointestinal bleeding in men was twice as high as in women across all age groups. The higher incidence of stomach ulcers in men compared to women may be attributed to men's greater consumption of cigarettes and drugs. Patients' average age at the time of gastric ulcer perforation was 65.7 years. Cheung et al. (24) noted that age, particularly between 60 and 79 years, is a predisposing factor for peptic ulcer perforation. In industrialized countries, the prevalence of Helicobacter pylori infection, followed by gastric ulcers, increases with age. This long-term inflammatory response against H. pylori in the gastric mucosa of older individuals may lead to permanent tissue damage, potentially laying the basis for gastric cancer (25, 26). The review by Alexander et al. (27) posits that the pathogenesis of gastric ulcers and gastric cancer is influenced not just by the presence of H. pylori, but also by the complex interplay of its virulence factors, the host's immune response, and the gastrointestinal microbiome. Our study findings revealed that 4.5% of patients had a history of continuous corticosteroid use for at least two weeks. Corticosteroid treatment is associated with an increased risk of gastrointestinal side effects such as gastritis, ulcers, and gastrointestinal bleeding. The estimated relative risk increase for gastrointestinal side effects with corticosteroid alone varies between 1.1 and 1.5 times accroding to Liu et al’s study. Concurrent use of corticosteroids and NSAIDs notably increases gastrointestinal event risks (28). Another finding of our research is that 67% of patients with perforated gastric ulcers had been taking NSAIDs. The excessive use of NSAIDs in these patients can be attributed to an increase in musculoskeletal pain and cardiovascular diseases associated with aging (refer to Table 2 ). NSAIDs have been identified as a potential risk factor for mortality following upper gastrointestinal bleeding, primarily caused by peptic ulcers, in various studies, including those by Sibilia and colleagues (29), Ben-Menachem and colleagues (30), and Straube and colleagues (31). However, Wu et al.'s study (32), involving 52,161 patients, revealed that regular NSAID use, particularly in patients with H. pylori-associated gastric ulcers, significantly lowered the risk of gastric cancer. This was evident in their observation that patients who never used NSAIDs had a higher risk of gastric cancer, while regular NSAID users showed a notably reduced risk. This is in line with our study's result; our study found that 66.9% of patients with perforated stomach ulcers were NSAID users, and importantly, none of these patients exhibited signs of malignancy in their gastric biopsies. This absence of malignancy in NSAID users with gastric ulcers aligns with and supports Wu et al.'s findings, suggesting a protective role of NSAIDs against the development of gastric cancer, especially in the context of H. pylori infection. In contrast, Li et al. (33) explored the impact of non-aspirin (NA-NSAIDs) on gastric cancer development in a large cohort of over 92,000 H. pylori-infected patients who had undergone H. pylori eradication therapy. This large-scale, territory-wide study used a time-dependent analysis to address potential biases. Contrary to previous meta-analyses that suggested a beneficial effect of NSAIDs (including both aspirin and NA-NSAIDs) on gastric cancer prevention, this study found that the use of NA-NSAIDs was not associated with a decreased risk of developing gastric cancer. This finding presents a contrasting perspective to the commonly held view of NSAIDs' protective role in gastric cancer development. Interestingly, 59% of patients with gastric ulcer perforation had a history of substance abuse. The study by Salemi et al. (34) also has shown a significant link between peptic ulcers and smoking. It seems that the mechanisms of tobacco and drug use in causing peptic ulcers are similar, and the continuation of these habits may lead to ulcer perforation. Smoking increases acid production and decreases bicarbonate and prostaglandin production, according to Ramakrishnan et al. (22). This can delay the healing of duodenal and gastric ulcers. In a study by Paragomi et al. (35) which investigated the association between PUD and Gastric Cancer by incorporating data from 11 case-control studies within their consortium, a significant link was established between gastric ulcers and an elevated risk of gastric cancer. However, no such association was observed with duodenal ulcers. Notably, it is essential to consider that pre-pyloric ulcers, a subtype of GU, carry the highest risk of perforation. Furthermore, the higher risk of non-cardia GC in patients with GU underscores the importance of specific and accurate diagnostic methods such as biopsy or gastroscopy, especially in cases with gastric ulcers. While our study did not investigate the location of the ulcer or the number of biopsy samples, these aspects could pave the way for future research. The decision to perform a biopsy can be made based on the doctor's preference, the patient's condition, and the availability of resources. Conclusions In this study, we exclusively examined patients with perforated pre-pyloric gastric ulcers and found no evidence of malignancy or gross masses in the collected samples. These findings suggest that biopsy procedures may be unnecessary for patients presenting with pre-pyloric gastric ulcers in the absence of any indicators of malignancy or noticeable masses. Therefore, we recommend more selective criteria for biopsies in future studies, potentially reducing the number of unnecessary invasive procedures for patients with similar presentations. Research Limitations The duration of gastric ulcer affliction was not examined and the study did not investigate cigarette smoking diet habits and presence of H. pylori. Recommendations for Future Research It's suggested that a study be conducted to explore the risk factors for perforation in patients with gastric ulcers. Given the number of samples in this study, it is recommended that future research involve more extensive sample sizes and include follow-up of patients after treatment and the healing of perforated ulcers.

A duodenal ulcer is typically characterized by severe upper abdominal pain that improves after eating. In contrast, gastric ulcers can cause pain that worsens after eating, often described as a burning or dull ache. Additional symptoms may include bloating, vomiting, weight loss, or loss of appetite (2). About one-third of elderly individuals with gastric ulcers do not exhibit any symptoms. A variety of factors can cause complications in patients with PUD, including Helicobacter pylori (H. pylori) infection, non-steroidal anti-inflammatory drugs (NSAIDs), and low-dose aspirin. These factors can lead to complications, including bleeding, perforation, and stomach obstruction, with bleeding occurring in approximately 15% of cases (3, 4).\u003c/p\u003e \u003cp\u003ePerforation, one of the most lethal complications associated with gastric ulcers, can develop in various locations, including the esophagus, stomach, duodenum, jejunum, and multiple segments of the small and large intestine (5). The inflammation and scarring resulting from gastric ulcers can further narrow the duodenum, resulting in symptoms of severe obstruction, vomiting, and sometimes hematoma formation. In certain cases, complications stemming from stomach ulcers can affect adjacent organs, giving rise to ulcers in the pancreas or liver (2, 6).\u003c/p\u003e \u003cp\u003ePre-pyloric ulcers have the highest perforation risk, followed by duodenal ulcers (5). The classic triad of abdominal pain, tachycardia, and abdominal rigidity characterizes gastric ulcer perforation (7). In many cases of PUD, surgical repair (either open or laparoscopic) may be necessary, although non-surgical approaches can be considered for selected patients (8). There can be a significant loss of fluid in patients with intestinal perforations. Depending on the type and volume of substances released from the digestive system, electrolyte imbalance can vary in severity. To minimize such disturbances, perforated patients require expeditious operative management (9).\u003c/p\u003e \u003cp\u003eRegardless of the type of surgery employed for local control or definitive ulcer surgery, obtaining a biopsy from the ulcer margin is crucial in all cases of gastric perforation to rule out gastric carcinoma (10). The significant distinctions between stomach and duodenal ulcers significantly influence patients' surgical decisions. Notably, gastric ulcers may carry a risk of malignancy, underscoring the importance of complete ulcer excision or, at the very least, conducting a biopsy through an open surgical approach. Furthermore, patients with gastric ulcers are typically older and have a higher number of risk factors, which increases the postoperative mortality risk within this patient group (11, 12).\u003c/p\u003e \u003cp\u003eAlthough less than 1% of gastric ulcers are premalignant, the relatively high incidence of cancer (9%) in cases of gastric perforation suggests that malignancy often underlies gastric ulcers in perforated patients (5). Given the elevated surgical risk associated with stomach ulcers, particularly in elderly individuals with multiple comorbidities, conducting a biopsy is crucial to confirm malignancy as the underlying cause (13). In our study, we performed biopsies on patients who arrived at the emergency room with clinical symptoms and approved diagnostic assessments suggesting a need for surgical intervention due to a perforated pre-pyloric gastric ulcer. During emergency surgery, we determined the frequency of confirmed malignancy by examining pathology reports derived from biopsies of the ulcer's wall, thus ensuring the diagnosis of a perforated pre-pyloric gastric ulcer.\u003c/p\u003e"},{"header":"Material and Methods","content":"\u003cdiv id=\"Sec3\" class=\"Section2\"\u003e \u003ch2\u003eStudy Design\u003c/h2\u003e \u003cp\u003eThis study employed a cross-sectional conducted at Sina Hospital in Tehran between 2021 and 2022.

These biopsy samples of 175 patients, underwent pathological examination to assess the presence of gastric malignancy. In addition to pathological findings, histopathological analysis aimed to confirm the existence of malignancy in various forms, such as adenocarcinoma, lymphoma, or stromal tumors. Independent variables were collected, including demographic information (age, sex), medical history (previous gastric ulcer disease, diabetes, hypertension, chronic kidney disease, and liver failure), and drug history (daily and continuous use of NSAIDs and corticosteroids for at least 2 weeks) and the presence of drug addiction among patients. Data for these independent variables were gathered using a researcher-designed checklist administered during the patient's initial hospitalization.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec6\" class=\"Section2\"\u003e \u003ch2\u003eData Analysis\u003c/h2\u003e \u003cp\u003eThe data collected was entered into Excel software for initial preparation.

closely linked with chronic inflammation (14). Stomach ulcers significantly contribute to these malignancies. Although biopsies are commonly used in perforated gastric ulcers in the pre-pyloric region, our study indicates a potential need to revise this strategy.\u003c/p\u003e \u003cp\u003eA key finding is the absence of malignancy and gross mass or tumor in gastric biopsies from patients with perforated pre-pyloric stomach ulcers, all showing benign pathology. This raises the question of whether biopsies are necessary for all cases, as accurate malignancy diagnosis in gastric biopsies requires a minimum of 8 samples from various parts of the lesion (15). Our research is among the few studies that examine malignancy rates in patients with perforated gastric ulcers. Comparing these findings with other studies is challenging due to the focus on peptic ulcer risk factors in other studies.\u003c/p\u003e \u003cp\u003eDue to this finding, the relationship between perforation and demographic or clinical variables couldn't be explored. However, chronic inflammation caused by Helicobacter pylori in patients with perforated peptic ulcers remains a significant medical concern in gastric cancer development (16). In the context of the relationship between H. pylori infections and gastric diseases, the comprehensive meta-analysis by Shirani et al. (17) is particularly enlightening. This study, encompassing 149 studies with a massive sample size of 352,872 individuals, delves into the global prevalence of gastric cancer among H. pylori-infected persons. Through extensive data extraction and statistical analysis, it sheds light on the prevalence and characteristics of gastric cancer in those afflicted with H. pylori. A vital aspect of this relationship is the role of specific bacterial features in causing cancer. Notably, certain H. pylori strains produce a toxin named CagA. Once injected into stomach lining cells, this toxin can induce carcinogenic changes, promoting cell growth and motility, leading to chronic inflammation. Epidemiological studies underscore that strains positive for CagA are more strongly associated with non-cardia gastric cancer than CagA-negative strains.\u003c/p\u003e \u003cp\u003eLifestyle factors also influence the risk of H. pylori-induced stomach cancer. Smokers infected with H. pylori, for instance, face a higher risk of developing stomach cancer compared to non-smokers with the infection (18). Additionally, diets high in salt and processed meats are linked to an increased risk of stomach cancer, potentially exacerbating H. pylori colonization and CagA entry into gastric cells (19, 20). Although our study did not evaluate lifestyle factors such as smoking, salt intake, and meat consumption, these aspects are crucial in understanding the overall risk landscape for gastric cancer in H. pylori-infected individuals. Therefore, it was essential to consider these factors alongside the biological characteristics of H. pylori and its interaction with gastric pathology.\u003c/p\u003e \u003cp\u003eIn our study, gastric ulcer perforation was more common in men than women, with the incidence of gastric ulcer perforation being 1.3 times higher in men. Comparatively, Bhattarai et al.'s (21) study found a 1.9 times greater prevalence of gastric malignancies in men than women. Similarly, Ramakrishnan et al. (22) reported the ratio to be 2 times higher in men. In their study, Hearnshaw et al. (23) also reported that the incidence of upper gastrointestinal bleeding in men was twice as high as in women across all age groups. The higher incidence of stomach ulcers in men compared to women may be attributed to men's greater consumption of cigarettes and drugs.\u003c/p\u003e \u003cp\u003ePatients' average age at the time of gastric ulcer perforation was 65.7 years. Cheung et al. (24) noted that age, particularly between 60 and 79 years, is a predisposing factor for peptic ulcer perforation. In industrialized countries, the prevalence of Helicobacter pylori infection, followed by gastric ulcers, increases with age. This long-term inflammatory response against H. pylori in the gastric mucosa of older individuals may lead to permanent tissue damage, potentially laying the basis for gastric cancer (25, 26). The review by Alexander et al. (27) posits that the pathogenesis of gastric ulcers and gastric cancer is influenced not just by the presence of H. pylori, but also by the complex interplay of its virulence factors, the host's immune response, and the gastrointestinal microbiome.\u003c/p\u003e \u003cp\u003eOur study findings revealed that 4.5% of patients had a history of continuous corticosteroid use for at least two weeks. Corticosteroid treatment is associated with an increased risk of gastrointestinal side effects such as gastritis, ulcers, and gastrointestinal bleeding. The estimated relative risk increase for gastrointestinal side effects with corticosteroid alone varies between 1.1 and 1.5 times accroding to Liu et al\u0026rsquo;s study. Concurrent use of corticosteroids and NSAIDs notably increases gastrointestinal event risks (28).\u003c/p\u003e \u003cp\u003eAnother finding of our research is that 67% of patients with perforated gastric ulcers had been taking NSAIDs. The excessive use of NSAIDs in these patients can be attributed to an increase in musculoskeletal pain and cardiovascular diseases associated with aging (refer to Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e). NSAIDs have been identified as a potential risk factor for mortality following upper gastrointestinal bleeding, primarily caused by peptic ulcers, in various studies, including those by Sibilia and colleagues (29), Ben-Menachem and colleagues (30), and Straube and colleagues (31). However, Wu et al.'s study (32), involving 52,161 patients, revealed that regular NSAID use, particularly in patients with H. pylori-associated gastric ulcers, significantly lowered the risk of gastric cancer. This was evident in their observation that patients who never used NSAIDs had a higher risk of gastric cancer, while regular NSAID users showed a notably reduced risk. This is in line with our study's result; our study found that 66.9% of patients with perforated stomach ulcers were NSAID users, and importantly, none of these patients exhibited signs of malignancy in their gastric biopsies. This absence of malignancy in NSAID users with gastric ulcers aligns with and supports Wu et al.'s findings, suggesting a protective role of NSAIDs against the development of gastric cancer, especially in the context of H. pylori infection.\u003c/p\u003e \u003cp\u003eIn contrast, Li et al. (33) explored the impact of non-aspirin (NA-NSAIDs) on gastric cancer development in a large cohort of over 92,000 H. pylori-infected patients who had undergone H. pylori eradication therapy. This large-scale, territory-wide study used a time-dependent analysis to address potential biases. Contrary to previous meta-analyses that suggested a beneficial effect of NSAIDs (including both aspirin and NA-NSAIDs) on gastric cancer prevention, this study found that the use of NA-NSAIDs was not associated with a decreased risk of developing gastric cancer. This finding presents a contrasting perspective to the commonly held view of NSAIDs' protective role in gastric cancer development.\u003c/p\u003e \u003cp\u003eInterestingly, 59% of patients with gastric ulcer perforation had a history of substance abuse. The study by Salemi et al. (34) also has shown a significant link between peptic ulcers and smoking. It seems that the mechanisms of tobacco and drug use in causing peptic ulcers are similar, and the continuation of these habits may lead to ulcer perforation. Smoking increases acid production and decreases bicarbonate and prostaglandin production, according to Ramakrishnan et al. (22). This can delay the healing of duodenal and gastric ulcers.\u003c/p\u003e \u003cp\u003eIn a study by Paragomi et al. (35) which investigated the association between PUD and Gastric Cancer by incorporating data from 11 case-control studies within their consortium, a significant link was established between gastric ulcers and an elevated risk of gastric cancer. However, no such association was observed with duodenal ulcers. Notably, it is essential to consider that pre-pyloric ulcers, a subtype of GU, carry the highest risk of perforation. Furthermore, the higher risk of non-cardia GC in patients with GU underscores the importance of specific and accurate diagnostic methods such as biopsy or gastroscopy, especially in cases with gastric ulcers. While our study did not investigate the location of the ulcer or the number of biopsy samples, these aspects could pave the way for future research. The decision to perform a biopsy can be made based on the doctor's preference, the patient's condition, and the availability of resources.\u003c/p\u003e"},{"header":"Conclusions","content":"\u003cp\u003eIn this study, we exclusively examined patients with perforated pre-pyloric gastric ulcers and found no evidence of malignancy or gross masses in the collected samples.

Given the potential for underlying malignancy in gastric ulcers and perforations, this study focuses on assessing the frequency of cancer in gastric biopsies of patients with perforated pre-pyloric gastric ulcers.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eThis cross-sectional study involved 175 patients of all ages, both genders, with perforated pre-pyloric gastric ulcers in 2021\u0026ndash;2022, who underwent emergency laparotomy surgery and with a definitive diagnosis of gastric ulcer perforation. A full-thickness sample was taken from the margin of the perforated pre-pyloric gastric ulcer for pathological examination to detect gastric malignancy.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eThe patients' average age was 65.69 years, with a median of 65 years. All histopathological examinations of the gastric ulcer samples indicated benign conditions. Among the patients, 54.3% had a history of gastric ulcers, 37.7% had diabetes, 25.7% had hypertension, and 25.7% had both. Additionally, 1.7% suffered from chronic kidney failure, 1.1% from chronic liver failure, and 0.8% had other conditions like cardiovascular diseases. In total, 4.6% patients had a history of corticosteroid use, 66.9% patients had a history of NSAID use, and 58.9% patients had drug addiction.\u003c/p\u003e\u003ch2\u003eConclusion\u003c/h2\u003e \u003cp\u003eOur study found no signs of cancer in the biopsies of patients with perforated pre-pyloric gastric ulcers; all cases showed benign pathology. This suggests that using gastric ulcer perforation alone as a reason for biopsy may need more investigation to ensure its accuracy and relevance.\u003c/p\u003e","manuscriptTitle":"Occurrence of Malignancy in Biopsy Specimens from Patients with Perforated Pre-pyloric Gastric Ulcers ","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-01-12 17:58:32","doi":"10.21203/rs.3.rs-3850897/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"021fd703-8237-4ca8-be43-e30470d0a9fd","owner":[],"postedDate":"January 12th, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2024-01-13T20:59:30+00:00","versionOfRecord":[],"versionCreatedAt":"2024-01-12 17:58:32","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-3850897","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-3850897","identity":"rs-3850897","version":["v1"]},"buildId":"qtupq5eGEP_6zYnWcrvyt","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
